The function r(x) = β0.000345(x β 50)2 + 2.1 can be used to model the curve of a road designed to allow for water to run off in rainstorms depending on the distance from the shoulder of the road, x, in feet. A European firm studying these curves is going to convert feet to meters using the function m(x) = 0.3048x. Which composition can be used to model the curve of the road in terms of meters? m(r(x)) = β0.000105156(x β 50)2 + 2.1 m(r(x)) = β0.000105156(x β 50)2 + 0.64008 m(r(x)) = β0.000345(0.3048x β 50)2 + 2.1 m(r(x)) = β0.000345(0.3048x β 50)2 + 0.64008
